contrib: make import-checker agree more with run-tests about heredocpy

run-tests.py and import-checker.py take wholly different approaches to
.t-tests, and the result was that they had different notions about
when a Python heredoc had ended, leading to conflicts. This resolves
part of the issue, and the rest I can deal with by tweaking the one
offending test file.
